So, I hadn't had a blockage since I had my surgery. Low and behold as soon as I ask a question about it I have one. It was only a partial blockage, but thank you all for posting your experiences because I knew what to do. It was VERY painful. I can't imagine what it would feel like if it was totally blocked.
I woke up at 4:00 AM with only a little in my bag (usually it is filled with gas and output) and in a lot of pain. I took a bath and did some crunches to see if I could get it moving. I also used the heating pad. All of a sudden my stomach was making these awful sounds like I have never heard before. It still hurt, but not as bad. By the time I went to work I was feeling better, but it was still very noisy. I had to tell some teachers that it was just me...nothing to worry about. They were blown away it was so noisy.
So, I think I will stay away from sweet and salty nut bars and I will chew a lot better. I don't want that to happen again.
Thanks all for sharing your stories, they come in handy.
